Anchor bolting your construction: Types and Practical Insights

Anchor fasteners serve as vital anchoring hardware in construction and engineering projects, securing objects to concrete or masonry surfaces. These specialised fasteners provide a secure anchorage that ensures structural stability and the safety of major buildings.

Let’s focus on anchor fasteners, their different types, their usage, and their significance in modern construction.

Understanding Anchor Bolts

Anchor bolts are designed to transfer the loads from the structure attached to it to the concrete or masonry substitute. It involves threaded ends for securing nuts and washers and a non-threaded part fixed in the concrete. The non-threaded end, also known as the portion, may have various configurations depending on the type and the specific application requirements.

Types of Anchor Bolts

They include the following:

Anchor Fastener Bolt

Anchor fasteners are made of steel and are used to secure objects to surfaces like concrete, masonry, or metal. 

Wedge Anchors

Wedge fasteners, also known as expansion bolts, are the most commonly used type of fastener. The latest innovation features a threaded end with a wedge-shaped expansion mechanism. Upon securing, it fits the wall of the pre-drilled hole, providing a sturdy hold and capturing the concrete for heavy-duty applications such as securing structural steel columns, equipment, and machinery.

Sleeve Anchors

Sleeve anchors consist of threaded screw fasteners enclosed in a cylindrical sleeve with an expansion groove or teeth. Users slip the sleeve through a pre-drilled hole, secure the screw, leading to the sleeve expanding until compressed. Besides walls and concrete, sleeve anchors are versatile and applicable to materials like brick and block. They commonly support fixtures, handrails, and signage on masonry surfaces.

Chemical Anchors

Chemical fasteners, also known as epoxy fasteners, rely on adhesive bonding to create a strong connection between the fastener and the substrate. They include a threaded rod inserted into a pre-drilled hole filled with epoxy resin. The epoxy cures to form a strong, firm bond, securing the fastener in place. These fasteners are ideal for applications that require loads beyond 2200 pounds, such as securing structural elements, reinforcing bars, and heavy equipment.

Applications of Anchor Bolts

• Structural Steel Construction: Structural steel construction typically relies on bolts to set up concrete fasteners for securing steel columns, beams, and bracing. These bolts, securely installed, not only ensure the structural strength of the building as a whole but also effectively withstand all lateral and wind stresses, as well as seismic impact. In high-rise buildings, bridges, and industrial structures, these fasteners are essential to hold these structures safe and stable.

• Equipment Installation: In industrial facilities, anchor bolts secure heavy equipment to concrete floors or platforms for safety and mechanical stability. These bolts prevent movement and vibration. This helps in ensuring safe operation and preventing damage to the equipment and surrounding structures. Anchor bolts are highly advantageous for anchoring machinery and maintaining operational efficiency, whether in manufacturing plants, warehouses or distribution centres.

• Architectural Features: Anchor bolts can serve architectural applications like attaching ornate panels, cladding, and canopies to a building’s exteriors. Such fasteners ensure secure mounting while maintaining the aesthetic integrity of the design. In commercial or residential areas, bolts play a crucial role in installing railings, awnings, and signage, enhancing functionality and visual appeal.

Use and Importance

• Structural Stability: Anchor bolts are important in making any building or infrastructure safe and stable, including high-rise structures. The use of anchor bolts firmly fixes objects onto concrete foundations or masonry surfaces, preventing displacement or joint separation. So heavy loads or wind forces cannot destroy the structural components. Maintaining the longevity and integrity of the construction project necessitates the indispensable feature of structural integrity.

• Load Transfer: Anchor bolts assist in the load-transferring process between the structure that links to the substrate, distributing forces evenly and minimising stress concentrations. They screw into the base to support large equipment, steel structures, or ornamental features. Additionally, developing such materials will enable them to bear heavy weights without structural failure and maintain the safety of occupants.

• Versatility and Adaptability: Anchors are available in different sizes and designs to cater to a variety of construction needs and site conditions, making it easier to select the best option. From the walls of concrete, brick, and cubic to grid-on-float, an anchor bolt solution is available to suit any application. Progress in anchor bolt technology, including rust-resistant coatings and high-strength reinforcements, enhances the ability to withstand corrosion and extreme conditions
